That's a 167 MiB chunk of memory you're allocating. Are you sure your DOS
extender (and underlying DOS) supports memory sizes like that?

The same allocate is successful in windows XP, but failed in Win 7 32Bit and
win server 2003, I'm not sure what's the different. I'm using 'cmd' command to
run this application. In my mind, If XP is OK, then the Win 7 32 bit should be
OK.

I think it shouldn't be a defect, the limit of DMPI caused this issue. You can
modified the dpmi limit to resolve this issue.
